Usually choose the buttocks with thick muscles and far away from the great nerves and blood vessels, which is often called "buttock injection" in life. In fact, you can also hit the deltoid muscle of the upper arm. The difference between it and intradermal injection is that the injected liquid is more irritating, the dosage is larger, and larger needles and syringes are used (1 ml syringe for intradermal injection and 2 ~ 5 ml syringe for intramuscular injection), and the needles are deeper and perpendicular to the skin surface.

Clinically, gluteus maximus, deltoid muscle and peptide biceps muscle are commonly used for intramuscular injection, but for intramuscular injection of specific parts of deltoid muscle, it is generally considered that it can be injected in the whole muscle. However, in many years of clinical practice, we have found that there are indeed some cases where the burning nerve and axillary nerve are damaged due to improper intramuscular injection, and there are also some cases that are directly beneficial to pulling nerve and gluing nerve. Right method 1: Thumb fixation: the patient is prone or standing, and the operator puts the middle finger and abdomen (the operator takes his left hand when injecting the left hip and his right hand when injecting the right hip) on the anterior superior iliac spine of the patient, and the thumb is parallel and bent backward, and the point where the fingertip touches is the injection point (about in the greater trochanter). Methods Two-line positioning: (1) Horizontal line: from the anterior superior iliac spine to the upper iliac spine. Fuck,
